The key that starts a CTRL-W command in a terminal window. Other keys are sent to the job running in the window. The <> notation can be used, e.g.: > :set termwinkey= < The string must be one key stroke but can be multiple bytes. When not set CTRL-W is used, so that CTRL-W : gets you to the command line. If 'termwinkey' is set to CTRL-L then CTRL-L : gets you to the command line.
